A temperature climatology has been developed for the surface and ten 10-m layers along the normal ship route between the eastern and western ends of Lake Superior and for discrete areas along the ship route. Base period for the climatology includes winters 1973-76 and falls 1976-79. Daily average temperatures and extreme temperatures for the base period were calculated, and a sixwave Fourier equation fitted to the average temperature time series to define the temperature climatology.
